This invention relates to apparatus; forf'pi'oducing threaded spangl'es,that is, threadsof spangles in which the individual span'gles arearranged and secured on a thread in 'flatwise position thereon, that is,with the opposite faces of the spangles lying against adjacent parts ofsaid thread. g v

This invention is concerned primarily with a meansfor feeding thespangles and the string on which they are strung to the machine whicharranges the spangles in said flatwise relation and which secures thespangles in said relation. However, the machine itself, which forconvenience in reference will hereinafter be designated as a spanglingmachine is known to those skilled in this art.

For convenience in handling, spangles which are to be arranged asindicated above fiatwise on a string threaded therethrough are firstmounted on supply strings in adjacent'face to face relation co-axiallyon their respective strings which are threaded through the spangleapertures, one supply string carrying say about two yardsof spangle's.In accordance with the present invention, the spangles are transferredfrom their'supply strings to the string on which they are to besecured'flatwise in the finished product. More particularly, pursuant tothe present invention the spangles are disposed in freely movablerelation on a string threaded through the. apertures of said spangles,and since in thefinished product the spangles are disposed .flatwise onthe string to which they are securedand which is threaded therethrough,the string must be of considerable length. For example, when eight yardsof spangles are disposed on the supply strings in co-axial relationadjacent to each other, in the finished product wherein, the spanglesare disposed flatwise, the length of the string. must be about 160 yardsfor spangles which areabout of an inchin diameter presupposing thenormal flatwise disposition of the strings. with the faces of adjacentspangles in slightly overlapped relation, as they usually are in thefinishedproduct. It will be understood that this long string must bepassed through the apertures. in thespang-les and fed into the spanglingmachine together with the spangles at the proper speed, By the presentinvention provision is made for feeding the string and the spanglesthrough which the string is threaded to the spangling machine in agreatly improved and advantag'eous manner. This constitutes one of theobjects of the presentinvention. Y

In fee ng the span'gles to the spangling Inathe apparatus;

chine, a number of 'spangl'e's are positioned adja' cent the intake ofthe machine in position to be moved by gravity into the machine. If toomany spangles are disposed at theintake of the ma chine the weight ofsaid spangles interfereswith the proper operation of the machineand'ther'e sulting product is frequently defective. This objecticin anddisadvantage is eliminated in ac"- cordance with the present inventionby providing means for limiting the number of spangles adjacent'theintake of the machine. I

The above and other objects of the machine -will best and more fullybeju'nclerstood from the following description considered with referenceto the accompanyingdrawings.

. Fig.9 is a View of the other side of the string of spangles' shown inFig. 8. Referring now to the drawings in detail, a multiplicity of the'spangles 1'0 are arranged "coaxially on part of a string l2 in freelymovable relation thereon, said string being threaded through theapertures of said span i'e's. Said string is ,of great length comparedto the combined thickness of all of the sp'afigles through whichSaid'string is threaded and is, therefore, for convenience wound foh aspool M as shown in Figs. 1,5 and 6, said string forming part (if thespangle-feeding apparatus illustrated in said figures of the drawingsand also in Figs. 2, 3 and fl. It will be understood that the spangle'sare initially furnished on supply strings, in lengths of say abo'uttwoyards of "spaifigleaafid that said span ies are transferred to rxidunnsgstring string.

guide rollers, particularly guide roller 22, being i mounted in elevatedposition above the intake I9 of the spangling machine, thearrangement'being such that string I2 slopes downwardly from saidelevated position thereof to the intake of said machine. String I2 isdrawn through the machine at the proper speed by the take-uproll 24 onwhich the finished string of spangles is wound, said take-up roll beingdriven by a pulley 26 in timed relation to the operation of the machine.Spool M is provided with a braking. device and forthat purpose has agrooved section 28 in fixed relation therewith which is engaged by atensioned cord 39. One end of said cord is fixed tothe standard asindicated at 34, and the other end' of said cord i fixed to one end 36of a metal link 38, the opposite end 40 of which is pivotally secured tosupport 35. End 36 of link 38 is connected to a weighted roller 42 whichis 5;

supported on thread I2, the weight for said roller being indicated at44. Additional weights 46 and 48 are connected to the end of link 38 andat a point intermediate said ends. The devices just described provideconvenient means for tensioning string I2 and for preventing the freerotation of spool It on the spindle, but any other suitable stringtensioning arrangement can be used instead. 1

The spangles H] disposed on string l2 move downwardly thereon over adownwardly inclined guide and support 50 mounted on vertical supports 52and 5,4. Said guide and support'5ll is as here shown in the form of atrough having opposite side walls 56 and a bottom 58. Side Walls .1

5S constitute guides for string I2and bottom 58 serves to support thespangles carried by said The spangles thus. move toward the 'spanglingmachine partly by gravity and partly by the string on which, they arecarried,' the movement of said spangles being retarded by the frictionalengagement of the upper surface of the bottom 58 of the chute with thespangles, .A roller 63 is positioned near the lower end of guide 50 andis rotated by a pulley 62 for assisting the movement of the spangles atthe lower end of said guide. String I2 and the spangles I9 thereon alsopass over a roller 64 driven by apulley 66. From roller 64 the spanglesIE] and the thread I2 pass to the inclined guide chute 68 of thespangling machine it; and from said guide to the intake I 9 of themachine.

As stated above, one of the objects and features of the invention is toprevent the accumulation of spangles 0n guides 88 in such numbers thatthe weight of the spangles would interfere with the operation of themachine. For this purpose provision is made for automaticallyinterrupting the movement of spangles on thread I2 .to supply guidechute 68 of the, spangling machine. The means provided for accomplishingthis result includes a barrier iii disposed at the lower end of guide 56adjacent roller 64. As here shown said barrier 16 is in the form of aforked member which is positioned so that the crotch I2 thereof I2 byattaching the end of the latter to the supengages the spangles on stringI2 and prevents movement of said spangles to guide chute 68 of thmachine. barrier I0 does not prevent movement of string I2 and thatconsequently the latter moves continuously so long as take-up roll 24 isrotated by the machine. Y rendered ineffective to prevent movement ofthe spangles to guide chute I58; For this purpose roller 64 is providedwith a member I4 fixed to said roller in position spaced radially fromthe hub I6 thereof. During each revolution of roller 64 member I4engages string I2 and raises said string above hub I6 of the roller toan elevated position such that the spangles slide down the string overand past the crotch of barrier ID to the guide chute 68 of the machine.Thus groups of spangles I0 are supplied intermittently to guide chute"68 of the spangling machine and the arrangement is such that the numberof spangles on the guide chute 68 at any one time is insufii- ,cient tointerfere with the operation of the machine; Fig. 2 shows the positionof roller 64' and more particularly member I4 thereof for eleva'ting thestring I2 so that the barrier is rendered ineffective to preventmovement of spangles to:

spangles to the guide chute but, as stated, permits the string to passfreely over the crotch of the barrier to thespangling machine. It willbe observed that roller 64 is driven in timed relation to the operationof the machine I and for that purpose the pulley 66 of said roller I isconnected by a beltlil to a pulley which is driven by the shaft whichrotates roller 60 and which is driven by pulley 62. A belt 82 connectspulley 62 to a driving pulley 82 which is fixed to and rotated by ashaft 84. Said shaft is driven by the main shaft 86 of the spanglingmachine and is connected by a belt 88 to the driving pulley 26 of theshaft which rotates take-up roll 24.

As stated above, the spangling machine I6 is of known construction andoperation and therefore requires no detailed description. It will beunderstood also that said machine. is supplied with strings of threadwhich secure the spangles in flatwise position on string I 2 which isthreaded and 94, respectively, being twisted in opposite directionsabout the thread 90a which is supplied frorn spool 90 and about thethread I2 which is threaded through the apertures of the spangles.Thread 90a is thicker than threads I2 and threads 92a and 94a and isdisposed with said last mentionedtwo threads 'as illustrated in Fig.9 onone side of the string of spangles, the other side of the string ofspangles having, as illustrated in Fig. 8, only thread I2 disposedthereon.

Thus, it is seen that the apparatus of the present invention is welladapted to accomplish the several objects 'thereof. It will beunderstood that the downward slope of the string on which the spanglesare carried to the spangling ma- It will be noted, however, that Thebarrier Ill is intermittently pursuant to the present invention, thedistance from roller 22 to the intake of the machine is about 34 feet,said roller is at a height of about '7 feet, roller 64 and barrier 10are about 3 feet below roller 22 and about 2 feet higher than the intakei 9 of the spangling machine and at a distance of about 2 feet laterallyof said intake. It will be understood, however, that these dimensions,while preferred, have not been established as critical and are not to beconsidered as limitative but only illustrative of the best mode of whichI am now aware for practicing my invention.

Accordingly, while I have disclosed the presently preferred embodimentof my invention, it will be understood that the invention may be embodied otherwise than as herein specifically shown or described and thatchanges may be made in the various partsof the apparatus and in thearrangement thereof. Therefore, I do not Wish to be limited to theembodiment of the invention here shown or to the specific constructionherein disclosed as embodiments of said invention except to the extentwhich may be required by the scope of the appended claims.
